Label_empty() got an unexpected keyword argument ‘label_cls’

Hi Sylvain,

Sure.

This post has an example: How do I predict a batch of images without labels

And here’s my example:

./test_set is empty except for the folder test/ which contains some images.

data=ImageItemList.from_folder('./test_set').no_split()
databunch=data2.label_empty().add_test_folder('test').databunch()

---------------------------------------------------------------------------
